Although the initial discount may sound tempting, be aware that the hhgregg credit card comes with a 29.99% interest rate. Also read the terms carefully as many store cards have a deferred interest policy which means if your entire bill is not paid in full by the agreement date it could be costly. Also hhgregg splits the payments equally over a specified period of time. So take into consideration that these payments will be higher than if you financed a purchase using a major credit card. If you have good credit there are many options that offer 0% promotional interest periods and also earn rewards.
